Description
Technical field
The present invention relates to a kind of independent hydraulic station controlling milling machine shifting system.
Background technology
Because XKF2320/4 profiling machine is longer for service life; system and each pipeline aging gradually; in process; frequent warning (alarm content: Gears change fault) is shut down; particularly heavily cutting, machete footpath adds man-hour, shut down frequent (start to process rear 2-3 minute and just report disorderly closedown) especially.Through observation and analysis repeatedly, determine that disorderly closedown reason is that lathe high and low shift signal lever falls, cause range state distortion, lathe is shut down.
XKF2320/4 shifting system of machine tools is made up of servomotor, shifting system (mechanism), speed-changing gear box.Wherein, shifting system (mechanism) is by a piston rod, two proximity switches, a shift fork connecting piston rod and provide the electric part of the hydraulic system of driving force and hydraulic control action to form for piston rod.
XKF2320/4 lathe when high-speed cruising, range piston bar at upper end position, in process; particularly heavily cutting, machete footpath adds man-hour, the vibration of lathe is relatively large, and piston rod slowly falls; when dropping to proximity switch SQ2 and detecting that high-grade signal is 0, lathe is reported to the police and is shut down.By analyzing whole gear change system, originally the CNC control system of lathe is after receiving the feedback signal of SQ2, and output interface DRT21 and DRT25 stops power supply immediately, and relay 2K2 and 2K6 disconnects immediately, and motor and magnetic valve end quit work.Magnetic valve mediates, and the pressure of piston rod pipeline is kept by magnetic valve chunk, pipeline, piston relative position.The seal request of this sealing to piston rod inner sealing ring, high-grade oil inlet pipe and joint thereof, magnetic valve chunk is high; once any portion in three parts has micro-leakage; the pressure of piston-rod lower end will slowly reduce; due to gravity factor; when piston-rod lower end pressure deduct upper end pressure be less than piston rod gravity time; piston rod will fall, thus cause lathe warning to be shut down.High-grade oil inlet pipe and joint were all looked into, and did not find leak point; Piston cylinder is overall, and lower end is connected with selector fork, cannot dismantle; Closely, dismounting needs the long period to the combination of magnetic valve group, cannot determine whether interior leakage.
Therefore, cannot judge under obvious cause situation, produce for recovering lathe as early as possible, shortening maintenance cycle, reducing maintenance cost, and the machine halt trouble because piston rod frequently falls to causing must be effected a radical cure, do not affect again other functions of equipment.So real to the transformation of XKF2320/4 milling machine shifting system is necessary.
Summary of the invention
When the machine halt trouble frequently falling to causing for milling machine shifting system cannot judge obvious cause, the technical issues that need to address of the present invention are to provide a kind of independent hydraulic station controlling milling machine shifting system.Producing to recover it as early as possible, shortening maintenance cycle, reducing maintenance cost, do not affecting on the basis of other functions of the equipments, solving its machine halt trouble.
For solving technical problem of the present invention, piston rod oil-in be realized and continue there is pressure, the electromagnetic valve work end continued power that control piston bar moves must be ensured and oil pump continuous firing, and the original electric control system of lathe cannot meet above requirement.
The technical solution used in the present invention is: the independent hydraulic station controlling milling machine shifting system, this independent hydraulic station comprises motor, oil pump, overflow valve, three position four-way electromagnetic valve and radiator fan, described oily Pump and Electromotor connects, screen pack is provided with between described oil pump and fuel tank, lathe gearshift pressure is controlled by overflow valve, the range piston bar direction of motion is controlled by three position four-way electromagnetic valve, has installed a radiator fan additional in oil pump oil-out position.
The running of motor is controlled by A.C. contactor KM3, and magnetic valve YT1 work of holding is controlled by contactor KM1 contact, and magnetic valve YT2 work of holding is controlled by contactor KM2 contact, and when lathe needs low-speed running, magnetic valve YT1 holds and machine operation; During machine tool high speed running, magnetic valve YT2 holds and machine operation; The work of the adhesive control oil pump motor of contactor KM3, low rate start button SB1 and high-speed starting button SB2 interlocks, and scram button SB3 is for cutting off power supply during gearshift.
Beneficial effect of the present invention: by the transformation to profiling machine shifting system; use this device can when obvious cause cannot be judged; effect a radical cure the machine halt trouble caused because piston rod frequently falls; ensure that its dynamic responding speed; improve dynamic responding speed and the equipment dependability of lathe shifting system; and significantly reduce maintenance cost, structure is simple, the operation that is easy to workman and maintenance, good economy performance.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.Following examples, only for illustration of the present invention, are not used for limiting the scope of the invention.
As shown in Figure 1, the independent hydraulic station of control milling machine shifting system of the present invention comprises motor 4, oil pump 3, overflow valve 6, three position four-way electromagnetic valve 7 and radiator fan 5, oil pump 3 is connected with motor 4, motor 4 drives oil pump 3 to pressurize and buys oil, be provided with screen pack 2 between oil pump 3 and fuel tank 1, lathe gearshift pressure is controlled by overflow valve 6, is about 3.5MPa, range piston bar 8 direction of motion is controlled by three position four-way electromagnetic valve 7, has installed a radiator fan 5 additional in oil pump 3 oil-out position.
In Fig. 1, overflow valve 6 adjusts oil circuit pressure and is about 3.5MPa, and pressure is observed by pressure meter switch I.
Whole hydraulic work system principle is as follows:
In Fig. 2, the running of motor 4 is controlled by A.C. contactor KM3, and magnetic valve YT1 work of holding is controlled by contactor KM1 contact, and magnetic valve YT2 work of holding is controlled by contactor KM2 contact.When lathe needs low-speed running, magnetic valve YT1 holds and motor 4 works; During machine tool high speed running, magnetic valve YT2 holds and motor 4 works.
Low rate start button is SB1, high-speed starting button is SB2, scram button is SB3, KM1, KM2, KM3 are contactor, the work of the adhesive control oil pump motor M of contactor KM3, low rate start button SB1 and high-speed starting button SB2 interlocks, and evade mistake when lathe is shifted gears and potential safety hazard, SB3 scram button can be used for power supply when cutting off gearshift.The process of gearshift is as follows:
Suppose to need top gear, press the button SB2, contactor KM2 adhesive, simultaneously, magnetic valve YT2 holds electric, contactor KM3 adhesive, Oil pump electrical machinery work, piston rod 8 moves, and pipeline constant voltage is 3.5MPa(Pressure gauge registration shows 3.5MPa always), when piston rod 8 moves on to position, proximity switch SQ2 detects signal, feed back to CNC system, machine tool chief axis starts to rotate; Need low grade to add man-hour, in like manner can operate.When considering machine tooling, oil pump 3, motor 4 are working always, therefore, a radiator fan 5 has been installed additional in oil pump 3 oil-out position, for the inner fluid of cold cut Hydraulic Station, control relay K M1 and any one adhesive of KM2 of high and low shift, radiator fan is work just.
Lathe shifting system is extracted separately, above 3 points be accomplished: 1, during gearshift, dynamic response wants fast; 2, ensure that piston rod oil-in continues there is pressure; 3, reduce maintenance cost and shorten maintenance cycle.
Lathe shifting system in shifting system of machine tools is extracted separately; controlled by independently Simple hydraulic station, and continue all the time to keep height gear oil-in to have pressure, piston rod can not fall; lathe also would not be reported to the police shutdown again, greatly improves production efficiency and the serviceability rate of equipment.
